The Qt framework's main user interface technologies are Qt Quick and Qt Widgets . Qt Quick interfaces are fluid, dynamic, and are best on touch interfaces. Qt Widgets are for creating complex desktop applications. You can create Qt Quick and Qt Widgets interfaces with the target platform's native look and feel.
Qt Quick is for creating dynamic and fluid user interfaces. The Qt Quick Controls module supplies QML types such as buttons, dialogs, and menus. You can use QML , a declarative language, to build the UI and JavaScript to implement the logic.

Qt Widgets are the user interface elements that are typical in desktop environments. The widgets integrate well to the underlying platform providing native look and feel on Windows, Linux and macOS. The widgets are mature and feature rich user interface elements suitable for mostly traditional user interfaces. In contrast to Qt Quick , the widgets are for creating large desktop applications and less suited for creating touch-centric applications with fluid interfaces.

The following table compares Qt Widgets and Qt Quick interfaces.
| Qt Quick / Qt Quick Controls | Qt Widgets | 注釋 | |
|---|---|---|---|
| 使用語言 | QML/JS | C++ | |
| Native look and feel |
|
|
Qt Widgets and Qt Quick Controls support native look and feel on their target platforms. |
| Custom styling |
|
|
Qt Widgets provide customization with style sheets and Qt Quick Controls has a selection of customizable styles . |
| 流暢動畫 UI |
|
Qt Widgets 無法很好地適應動畫伸縮。Qt Quick 提供瞭按聲明方式實現動畫的方便且自然方式。 | |
| 觸摸屏 |
|
Qt Widgets often require a mouse cursor for good interaction, whereas Qt Quick provides QML types for touch interaction. | |
| 標準行業 Widget |
|
Qt Widgets provide all the bells and whistles, developed over two decades, needed for building standard industry type applications. | |
| 模型/視圖編程 |
|
|
Qt Quick 提供方便視圖，但 Qt Widgets 提供更方便且完整的框架。除 Qt Quick 視圖外，Qt Quick Controls 還提供 TableView . |
| 敏捷 UI 開發 |
|
|
Qt Quick 是敏捷 UI 原型設計和開發的絕佳抉擇。 |
| HW (硬件) 加速圖形 |
|
|
Qt provides full hardware acceleration for Qt Quick interfaces and Qt Widgets interfaces are rendered in software. The 圖形 overview has more information. |
| 圖形效果 |
|
Several Qt Quick modules provide graphical effects and Qt Widgets interfaces can use Qt GUI for effects. | |
| 富文本處理 |
|
|
目前，Qt Widgets 為實現文本編輯器提供最綜閤基。Qt 的富文本文檔類還可以用於 Qt Quick 和 Qt Quick Controls 的 TextArea ，但可能要求一些 C++ 實現。 |
